Light geomagnetic turbulence expected.
Right now the Kp index sits at a calm 0.7. Activity may climb to Kp 4 within the next few hours.

Do magnetic storms affect blood pressure and heart rate?
Research links geomagnetic activity to small statistical shifts in heart rate regulation, and one large dataset finds population blood pressure fluctuations sharing rhythms with it — but the measured effects are group averages, far too small to read off a single home reading.

Can a magnetic storm cause insomnia?
Chronic insomnia is defined by months of disturbed nights, while a geomagnetic storm lasts hours — so the storm itself is a poor explanation. The weak melatonin evidence, the far stronger role of bedtime expectation, and how to check your own pattern.

Why do fatigue and weakness increase during a magnetic storm?
The tiredness is real, but the magnetic field is one of the weakest suspects: the best human evidence links storms to reduced heart rate variability, not to fatigue itself, while lost sleep, air quality and expectation sit on exactly the same day with far stronger credentials.

Can a magnetic storm cause a headache?
Large-scale research has failed to find storm-driven headaches — 63 million headache reports produced a correlation of almost exactly zero — while falling barometric pressure, humidity, rain and lightning all leave measurable traces in headache data.

Quick answers about the Kp index, how geomagnetic storms may affect weather-sensitive people, and how our forecast works.
What is the Kp index?
The Kp index is a 0–9 scale of global geomagnetic activity measured by ground magnetometers. Values of 5 and above mark a geomagnetic storm (NOAA levels G1–G5). We update it from NOAA SWPC and GFZ Potsdam data.
How do storms affect wellbeing?
Some people report headaches, fatigue, poor sleep or mood changes around strong geomagnetic activity and rapid pressure swings. This is a correlation, not a medical diagnosis — we simply help you notice patterns and take it easy when activity is high.
What to do during a magnetic storm?
Research may describe possible correlations between environmental conditions and wellbeing, but Kp is not a symptom probability. MeteoStorms does not diagnose, predict an individual's symptoms, or replace qualified medical advice.
How does the forecast work?
Our forecast combines NOAA SWPC space-weather models with live solar-wind and Kp readings to estimate geomagnetic activity for the days ahead. It shows the expected Kp range and NOAA G-level so you can plan ahead.
